I wasn't suggesting that you not QT the fish. LOL I was just saying I didn't think the shrimp needed to be QT'd.
BTW, in my opinion, unless you use your QT tank for a full 4 week period for each new fish, you aren't really quarantining them. Marine ICH and velvet for instance, have a three to four week cycle. QTing for a few days and then putting them in your display isn't a "true" QT period, as it might take a week or more for any symptoms to become apparant.
And I don't quarantine. Maybe its a major "no-no", but my tank already has ich (as previously disclosed when I sold my Hippo Tang). Since that outbreak three months ago and the Herbtana treatment + fortified food, there has been no additional sign of it. My personal experience w/ QT is that it is stressful for the fish to be in a sterile environment with fluctuating water parameters (I found it very difficult keeping a 10 gallon stable) - and I'd have to buy a 50 - 75 gallon complete setup just to remove all my fish to let my 90 run fallow for 6 weeks - and thats not gonna happen! But thats my choice - be it right or wrong in someone else's eyes.
